SPECIFICATION forming part of Letters Iatent No. 552,595, dated January 7, 1896.

Application filed March 6,1896. $erial No. 540,728. (No model.)

To all whom it may concern.-

Be it known that we, EDDY T. THOMAS, a resident of the city, county, and State of New York, and ALEXANDER MELHAno, a resident of Montclair, Essex county, and State of New Jersey, citizens of the United States, have invented a new and useful Improvement in' Dumping-Cars, of which the following is a specification.

The object of this invention consists in providing a coal-car with facilities for unloading the car.

The invention consists in a rack and pinion, rack-links, pinion-flange, surface-plate, rack-lock, and shaft-guard.

Figure 1 represents an ordinary coal-car having the improvements applied. Fig. 2 is a side view of the rack. Fig. 3 is the left or opposite rack. Fig. 4 is the surface plate. Fig. 5 is an end view of Fig. 4. Fig. 6 shows the pinions and shaft. Fig. 7 shows how the lock may be applied vertically. Fig. Sis a side view of Fig. 7. Fig. 9 shows how the lock may be made to swing horizontally. Fig. 10 is a side viewof the rack shown in Fig. 9. Fig. 11 is a top view of the lock shown in Fig. 9. Fig. 12 is an enlargedview of the lock shown in Fig. 9. Fig. 13 shows the shaft and the guard, and Fig. ltrepresents the racklink. i i

A in the severalfigures represents a clumpcar for coal, grain, and other commodities. This car is of usual construction, having a frame A,an inclined floor A extending below the main body of the car and secured to the side A trapdoor A hinged at A and sup porting-timbers A".

. 13 in the several figures is a rackhaving teeth'B, which engage with the pinion F.

B Figs. 1, 2, 8, and'lO, are lugs cast or set into the wings of the lower end of the rack at D, Figs. 1, 4, and 5, are surface plates supporting the several parts and holding them in place, the wood of the car not being of sufficient strength.

D is a lug which in connecshaft is turned until the doors are tion with the pinion F supports the rack B in a vertical position in the space B of the plate. The lug D forms a pivot for the pawl or lock G, Fig. 1. The hole D is for a bolt to fasten the plate to the car, while the recess D is for the pinion-shaft E. i

F, Figs. 1 and 6, are pinions secured to the shaft E and operate the rackB. These pinions are provided with caps F, which extend over the racks B and hold them firmly against the surface plate D.

The pawl or lock-bar G (shown in the several figures in different forms) is to prevent the rack-bar B from being forced down and causing the doors A to open while the car is loaded or in transit, The spring G, Figs. 1, 9, and 11, operates against one end of the pawl or lock-bar G and automatically fastens the rack bar to its highest position, as shown in Fig. 1, by the pawl or look catching in the recess B, as shown in Figs. 1, 2, 3, 7, 8, and 10.

The recess 13, Figs. 2 and 10, of the rack bar is to allow a clearance for the surface plate D, as shown in Fig. 1, while the lugs 13- and B prevent the rack-bar from being forced down or up too far.

To prevent the accumulation of ice and coal on the shaft E a pipe E is slipped on, as shown in Fig. 13, being of sufficient size to leave a space E, as shown at E that the shaft may have a free play. E Fig. 13, shows how the top part of the shaft may be covered.

WVhen the car is to be unloaded, the pawl or look G is released from the rack-bar B, and

the shaft turned until the trap-doors A are thrown open, as shown by the dotted lines in Fig. 1. After the car has been emptied the closed and the rack-bar locked. 1

While a recess B is shown in Figs. 1, 3, and

- face plate D, in combination with the rack bar B, having recess B and pivoted links 0, cperated bythe pinion F, and locked by the pawl G, as and for the purpose described.

2. The car A, having hinged doors A, and surface plate D, in combination with the rack bar 13, having recess 13, and lugs B", and B and link 0, operated by the pinion F, as and for the purpose described.

3. The car A, having doors A", and surface plate D, in combination with the rack-bar B, having recess 15, and pivoted links C, operated by the pinion F, and automatically locked by the pawl G, having spring G as and for the purpose described.

4. The car A, having doors A and surface plate D, the said surface plate D, being pro vided with holes D for supporting the arbor E, and pinions F, alugD',forholding the rackbar B, vertically and constantly against the pinion, and a lug D on which the pawl G, is pivoted, in combination with the rack-bar B, having recess B, and pivoted links C, operated by the pinion F, and locked by the pawl G, as and for the purpose described.

5. The car A, having doors A, and surface plate D, in combination with the rack-bar 13,

having recess B, and provided with links 0, operated by the pinion F, the said pinion F, having cap F, to hold the rack-bar B, firmly against the plate D, and the pawl G, for looking the rack-bar B, as and for the purpose described.

6. The car A, having doors A, surface plate D, and arbor E, covered by the pipe F for preventing ice and coal from forming on the arbor E, in combination with the rack-bar 13, having links 0, operated by the pinion F, mounted on the arbor E, and the pawl G, for locking the rack-bar B, as and for the purpose described.

In testimony that we claim the foregoing as our invention we have signed our names, in presence of two Witnesses, this 23d day of February, 1895.
